Who introduces the manufacturer of water-cut sealing strips for automobiles?

Hello, I know some information about automobile sealing strip industry. Expensive, very good, basically foreign-funded, such as Shanghai Shenya, Beijing Wanyuan Hande (the previous two were joint ventures, and now all of them are foreign-funded shares), not to mention Japan and South Korea. State-owned enterprises include Hongyang Seals under Guihang, German-owned Sagumi acquired by Chongqing Textile Group, private enterprises including Zhao Jianxin and Chineydy in Zhejiang, Hebei Shida Seals Group and Hebei Xinhua Group. Generally speaking, foreign capital is more expensive. Private enterprises mainly belong to supporting domestic cars, with acceptable quality and price, and are constantly improving, not necessarily worse than foreign capital, involving many aspects.
